In places with cold winters an office/classroom may have some paid for heating but your home may not. This means that even if you get some sort of a heater in your dorm or appartment, you may feel cold and under the pressure to spend more money than you expect during the cold spells. Utilities in nations such as China where winters in provinces such as Hunan may, and currently are, quite cold, and so they may go over 150 dollars per month. Therefore, I urge all readers who plan to assume their employment in some parts of the world to check their employment agreements for terms and conditions not to be surprised one day.
